Title: Small electric motor, especially for windscreen wiper installations in motor vehicles
Inventor: SCHNEIDER THEODOR
IPC: H02K7/116
Filed: 1982-03-18
Abstract: In a small electric motor having a cylindrical motor housing, having a transmission housing (11) which has a bearing plate (16) to which the motor housing is flanged and a flat pot (13) whose axis runs at right angles to the centre axis (33) of the motor housing, and having two slides (40), which lie with their longitudinal direction in the axial direction of the pot (13), in holders (55) in the bearing plates (16), and are in each case held against a stop on the motor housing by a screw which passes through the bearing plate (16), it is intended to simplify assembly. As can be seen in Figure 2, this is achieved in that at least one slide (40) and its holder (55) are arranged laterally offset on the bearing plate (16), so that a centre line in the longitudinal direction of the slide (40) and the centre axis (33) of the motor housing are skew with respect to one another. In such an arrangement, projections (17) on the transmission pot (13) can no longer interfere during assembly. On the other hand, the tool for producing the transmission housing (11) is no more complicated. <IMAGE>
Patent DE-3211021-A1 (DE)
Inventor: MEISSER CLAUDIO DIPL ING
IPC: G01F1/66
Filed: 1982-03-25
Abstract: In a housing two ultrasonic measuring transducers are arranged opposite of the two end faces of a test tube. The test tube providing a measuring section penetrates a separating wall and interconnects two distribution chambers of the housing. The fluid to be measured flows through the test tube and influences the transit time of the ultrasonic impulses released and received by the measuring transducers. The test tube provides a constant cross-section of metallic material along the length of the measuring section. The connection between the test tube and the separating wall consists of a nonmetallic material, thus preventing echoes which may penalize the measuring accuracy.

Patent DE-3334240-A1 (DE)
Title: Method and circuit arrangement for measuring an ohmic resistance
Inventor: WENZEL ROBERT DIPL ING
IPC: G01R27/14
Filed: 1983-09-22
Abstract: To measure an ohmic resistance at the end of a two-wire line, an alternating voltage or an alternating current is fed in via a transformer. The frequency of the alternating voltage fed in or of the alternating current fed in is selected in such a manner that its corresponding wavelength is much greater than the length of the line. The characteristic impedance of the line is much lower than the ohmic resistance to be measured. In the resonant circuit consisting of the operating capacitance of the line, of the main inductance of the transformer and a capacitor connected in parallel with the input of the transformer, a resonance is produced by changing the capacitance of the capacitor. The parallel resonant circuit consisting of the operating capacitance of the line and the main inductance of the transformer can also be brought to resonance by changing the frequency. In the case of resonance, the voltage at the input of the transformer is proportional to the value of the resistance to be measured when current is fed in.

Title: Welding stud
Inventor: KNEISSL ANDREAS
IPC: B23K35/02
Filed: 1983-11-05
Abstract: In a welding stud with a welding tip, a thread and a flange arranged between welding tip and thread, the flange surface facing the thread is designed as a bearing surface for a component to be fastened. Owing to the fact that during fastening of the component by means of a nut the frictional connection takes place only between nut and flange, the welding spot remains free of tensile loads. The welding tip is preferably dimensioned in such a way that, after the welding stud is welded on, a pedestal remains between the base carrying the welding stud and the flange so that, during subsequent painting, the paint can readily penetrate between the flange and the base.

Title: Method and device for adjustment of the fuel-air ratio in combustion engines
Inventor: MORITA TATSUO
IPC: F02D41/14
Filed: 1983-12-19
Abstract: An air-fuel ratio control device determines that value of the mixture ratio at which even engine running changes into uneven running. As long as the engine is running evenly, that is the running out of true lies within an admissible range, the mixture is made increasingly leaner. If, on the other hand, engine running out of true in an inadmissible range is detected, the mixture is enriched in a predetermined manner in order to prevent uneven running. The enrichment occurs until running out of true is inside the admissible range again. The control device can be used on all combustion engines.
